13.3 PlanAhead - Resource estimation on Gigabit Transceiver is not correct

Description

When I run Netlist resource estimation, it shows that the design uses More transceivers than should be in my design.

Example:

135 out of 155 GTs used when only a few are used in the design.
137 out of 137 GTs used when no transceivers are used in the design.

Where are the GTs coming from?

Does the devicehave this many GTs.

Solution

The Resource Estimation is showing an incorrect value for both the number of GTs used and the number of GTs available on 7 Series devices.

This is an estimation report only issue that is fixed in ISE Design Suite 13.4.
